Course Description:

Physics 160 surveys important developments in physics during the twentieth century.  The first portion of the course deals with the modifications to mechanics that came with the introduction of the theory of relativity and quantum mechanics.  The objective is to reach both a conceptual familiarity and quantitative capability in approaching the subject.  The remainder of the course deals with important applications and extensions of these ideas to atoms, solids, nuclei, and elementary particles.  As we survey applications, our approach will become more descriptive and less quantitative so that we can obtain an overview of some of the major accomplishments of the twentieth century. We selectively focus on developments growing out of quantum mechanics and relativity and neglect other contemporary topics.

Course Objectives:

Required Text:

·        Paul A. Tipler, Ralph A. Llewellyn, Modern Physics, 4th Ed. , Freeman).  Obtain this text from Conkey's Bookstore on College Avenue.

Other Required Materials:

·        National Bound Notebook No. 43-648 (or similar with numbered quadrille ruled pages)).  Available at Conkey's Bookstore.

·        Calculator with trigonometric, logarithmic, and exponential functions.

·        A three-ring binder to keep your lecture notes, handouts, and laboratory information pages (recommended only).

Grades:

Final grades will be based on the following weighted components:

1) Final Exam 25 %

2) Hour Exams (2 X 12.5%) = 25 %

3) Laboratory 25 %

4) Homework 15 %

5) Participation, Preparation, & Attendance 10%

 

Exams:

There will be two midterm exams and one final, comprehensive exam. Each exam will be closed book.  Required formulae will be provided on the exam, but you will need to be able to recognize the meaning of the symbols in each formula and how to use them to solve problems such as those encountered in homework and lecture examples.  Exam problems will be a mixture of quantitative problems like those encountered in homework sets and conceptual problems (multiple choice and short answer) like those used for in-class discussions.

Final Exam: Tuesday 5 June 2007, 1:30 PM

Laboratory:

The list of laboratory topics for each week is given below.  Details on the operation of the laboratory portion of the course, including grading policies for labs, will be discussed at the first meeting of the lab section.

Homework:

Homework sets will be collected for grading approximately once per week.  Late submissions may not receive full credit and may not be graded in a timely manner (if at all).  Homework assignments will focus on quantitative problems.  You are strongly urged to work additional problems on your own, beyond those that are required.  You are also encouraged to work together and to take advantage of evening help sessions and instructor’s office hours.  However, each student must write up his or her own solutions.  It will be detrimental to your exam performance to rely heavily on your classmates for homework solutions.  Complete solutions to homework problems often include the following elements:  statement of the problem (what is given?), appropriate diagram, reference to important laws or formulae, brief explanation and/or justification for each major step in the solution, evaluation of the final answer (does the answer makes sense?).

Preparation, Attendance, & Participation:

·        Prepare for class by reviewing your lecture notes from the previous class, reading the appropriate sections of the text, attempting some of the homework problems, and writing down questions or points of confusion.

·        Attendance in this fast-paced course is crucial.  We cannot cover everything in your textbook.  You must attend class (and work homework problems) to know what material your instructor considers essential.  Take notes in class.

·        Participate in classroom discussions.  Ask questions in class. Be prepared to respond to the instructor’s questions in class.  Make use of the instructor’s office hours and the evening help sessions. E-mail questions and comments to your instructor (stonekim@lawrence.edu). 

Help Sessions:

Evening help sessions will be offered every week.  These sessions will be held in Youngchild 115.  Times will be announced in class.
